however, in the video He took off more than he needed to. Just take the big nut off and the two small bolts to take the egr valve all by itself and leave the engine part where it is. (just look at the new part and you will be able to see what should come off.

The video is great but I need to know the specific size of the wrench used. In my case, the egr is attached to the block next to the Iac valve with the tubing directly attached to the valve with a large nut.
